I’m new to this group, I’ve done searches looking for info for this, but have found none, so here goes: I’d like to use AOG to provide autosteer on an IH 1486 tractor, a last year production, so it has closed center hydraulics. That said, I’d guess this would be very similar to the 5000 series that follow in 1982, so that information would be helpful as well. What steering valve has been used to provide autosteer, autosteer override/shutoff?
I believe you need to check the orbital motor, Does it have 4 or 5 hoses attached?
4 hoses would suggest it is Open Center Like the one shown in my link.
Steering can still be OC , while the rest is CC
I’m fairly new here myself and hoping to do the same thing with a 1586. I am certain your steering is OC as it uses a different pump than the remotes which very well could be closed center in your case.
their is an active thread on here titled (Question interest in steering valve block) I find it interesting I think you will too
See this thread on my 5488 install.
I had 2 Baraki open center 30 l valves running on planting tractors in 2024; one on a 5488 and one on a 5088. I’m gradually upgrading the fleet to newer MX Magnums, but I had good success with AOG and the Baraki valve on the 88’s.
The pumps between the 88’s and 86’s are a bit different, but i think the steering circuit is essentially the same from the autosteer valve’s perspective. The 88’s have a priority valve that directs a fixed amount of flow to the steering and brakes, and behaves like an open center circuit. Not sure if that’s the same on 86’s, but I do know that both 86’s and 88’s have 4-port orbitals.
Here’s another thread that might be helpful that includes a schematic and description of how the Baraki valve is plumbed into my 88’s.
Side note: I had a bit of a nightmare scenario with the valve initially essentially due to a defect in the machining of the valve block that blocked oil flow to the autosteer valve. That said, I think that was 1 in 1,000,000, and I was very happy with the support of Baraki and the community to work through it. I’ve bought 2 valves since that fiasco from Baraki.
It does have four connections, so open center for steering
it is open center steering
